RISHigh Spatial Resolution Crack Monitoring in Concrete Structures Using a Distributed Fiber Optic Sensor
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A method to monitor the mechanical behavior and identify crack location and growth in a concrete structure element using a distributed fiber optic sensor (FOS) system is demonstrated experimentally by testing concrete ...
Statistical Characteristics of a Real-Time Precipitation Forecasting Model
Publisher: American Meteorological Society
Abstract: At Colorado State University the Regional Atmospheric Modeling System (RAMS) has been used to produce real-time forecasts of precipitation for the Colorado mountain region since 1991. Originally a so-called dump-bucket ...
Assessment of Hydrometeor Collection Rates from Exact and Approximate Equations. Part II: Numerical Bounding
Publisher: American Meteorological Society
Abstract: Past microphysical investigations, including Part I of this study, have noted that the collection equation, when applied to the interaction between different hydrometeor species, can predict large mass transfer rates, even ...
Low-Level Mesocyclonic Concentration by Nonaxisymmetric Transport. Part I: Supercell and Mesocyclone Evolution
Publisher: American Meteorological Society
Abstract: An idealized simulation of a supercell using the Regional Atmospheric Modeling System (RAMS) was able to produce a low-level mesocyclone near the intersection of the forward- and rear-flank downdrafts. The creation of the ...
Assessment of Hydrometeor Collection Rates from Exact and Approximate Equations. Part I: A New Approximate Scheme
Publisher: American Meteorological Society
Abstract: The collection equation is analyzed for the case of two spherical hydrometeors with collection efficiency unity and exponential size distributions. When the fall velocities are significantly different a more general form ...
Effect of Orientation and Size of Helley‐Smith Sampler on Its Efficiency
Publisher: American Society of Civil Engineers
Abstract: Two series of laboratory experiments were conducted to evaluate the influence of mean flow direction and sampler size (7,6 cm aperture vs 3 cm aperture) upon the efficiency of Helley‐Smith samplers in subcritical flows. ...
Low-Level Mesocyclonic Concentration by Nonaxisymmetric Transport. Part II: Vorticity Dynamics
Publisher: American Meteorological Society
Abstract: An idealized supercell simulation using the Regional Atmospheric Modeling System (RAMS) produced an elongated low-level mesocyclone that subsequently collapsed into a concentrated vortex. Though vorticity continually ...
Joining of Zirconium Alloys to Nickel Bearing Alloys for In-Core Components
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Zirconium alloys are well-positioned as the material of choice for nuclear in-core structures since they have a low neutron absorption cross section and possess good material properties under elevated neutron flux and ...
Various Design Aspects of the Canadian Supercritical Water Cooled Reactor Core
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The Canadian Supercritical WaterCooled Reactor (SCWR) is a 1200آ MW(e) channeltype nuclear reactor. The reactor core includes 336 vertical pressurized fuel channels immersed in a lowpressure heavy water moderator and ...
Submeso Motions within the Stable Boundary Layer and Their Relationships to Local Indicators and Synoptic Regime in Moderately Complex Terrain
Publisher: American Meteorological Society
Abstract: o better understand the physical processes of the stable boundary layer and to quantify ?submeso motions? in moderately complex terrain, exploratory case-study analyses were performed using observational field data ...
